Analysis of Concrete Machinery Mixer’s Part- Hydraulic system

When talking about Hydraulic system of Concrete Machinery Mixer, you may puzzle about it or just heard little before, and i will tell you something about it. Hydraulic system consists of voltage, speed, reversing, locking, balance, brake, multi-cylinder unloading and other basic circuits, whose performance characteristics are:

1) Balance the circuit, using an improved one-way valve for balancing valve pilot order to prevent the lifting, telescopic boom and luffing operation process due to heavy weight decreased, and stable and reliable, but back pressure in one direction, the system will cause some power loss.

 

2) In the regulator circuit, using a safety valve to limit the maximum working pressure, prevent system overload, overweight lifting crane to achieve security protection.

 

3) in the speed loop, manually adjust the valve opening to adjust the size of the workpiece institutions (except landing mechanism) speed, convenient and flexible, fully embodies the people-oriented, employing directly manipulating apparatus ideas.

 

4) in a locked loop, two-way hydraulic lock by a check valve consisting of front and rear legs locked in a certain position, reliable, safe, and ensure that the entire lifting process, each leg will not appear soft leg of the phenomenon, even if the engine stalling or hydraulic pipeline rupture occurs, bidirectional hydraulic lock can still work, and long lifetime.

 

5) In the brake circuit, Mini Mixer Truck using the one-way throttle and brake single acting brake cylinder configuration, use the adjusted spring force brake, brake, reliable, fast action, due to the use of hydraulic cylinder compression springs loose open brake, brake release and therefore the action is slow, prevented weight lifting when the slip car phenomenon, to ensure safe lifting, and died when a fire truck engine or hydraulic system failure, can quickly achieve brake, prevent lifting The heavy fall.

 

6) In the multi-cylinder unloading circuit, the use of multi-valve structure in which each of the three median function of the four-way manual valve are M-type median function, and the valve in the circuit in series up and use, so you can make any one job agency operates independently; this tandem structure can also be any combination enables organizations to operate simultaneously at light loads; but with six valve connected in series, will pump unloading pressures, reduce system efficiency, but because the crane was not frequently work machine, these losses have little effect on the system.
